Job Description:

As a Generative AI Intern, you will join Wiremind's emerging GenAI team and work directly under the supervision of our Lead GenAI Engineer. You'll contribute to developing LLM-powered features (most likely in Cayzn) that help airlines and railways make better pricing and operational decisions. Our team is building LLM-based systems to analyze services (flights, trains), recommend pricing actions, and help revenue managers define automated strategies using natural language.

Job Responsibility:

  • Design and run experiments to test different approaches for the projects
  • Prompt engineering through systematic testing and refinement
  • Develop evaluation frameworks including 'LLM-as-judge' approaches and metrics aligned with expert preferences
  • Benchmark LLM models (GPT-4, Claude, etc.) to find optimal cost/performance tradeoffs for production constraints
  • Break down complex problems into simpler, specialized sub-tasks that LLMs can handle more reliably
  • Analyze failure modes and edge cases in LLM outputs
  • Document and share your findings with the broader engineering and product teams

Requirements:

  • Currently pursuing a Master's Degree in computer science or data science
  • Solid Python programming skills and experience working on structured projects
  • Experimented with LLMs (personal projects, coursework, hackathons) and eagerness to learn more
  • Good understanding of fundamental machine learning concepts and evaluation metrics
  • Curiosity about applying AI to solve real business problems in production environments
  • Strong analytical skills and enjoy iterative experimentation
  • Clear communication and ability to explain technical concepts to non-technical stakeholders

Nice to have:

  • Familiarity with prompt engineering best practices
  • Interest in revenue management, pricing, or optimization problems
What we offer:
  • 1 day of remote work per week
  • A great company culture (monthly afterworks, regular meetings on technology and products, annual off-site seminars, team-building…)
  • Beautiful 900 m² offices in the heart of Paris (Bd Poissonnière)
  • A caring and stimulating team that encourages skills development through initiative and autonomy
  • A learning environment with opportunities for evolution
